Abstract

Bottled water like any drinking water used for human consumption should be safe and of standard quality to ensure adequate public health significance. This study is aimed at assessing the physicochemical quality of some bottle water sold in Kano Metropolis. Studies on physicochemical parametric analysis were conducted. A total of 40 samples comprising of 4 different brands were randomly selected from different location. Physicochemical parameters of water samples such as Temperature, pH, Electrical conductivity, Total dissolved solids, turbidity, Magnesium, Calcium, Lead, Copper, Zinc, Bicarbonate, Chloride, Nitrate and Phosphate were analyzed using standard methods of water analysis. The Results of physicochemical parameters were within the drinking water regulatory standard. However, zinc, lead and copper was found to exceed the bottle drinking water standard in the ranges of 3.91 – 6.17Mg/l, 0. 29 – 0. 47Mg/l and 1.54 – 2. 67Mg/l respectively; thereby rendering the water unfit to human consumption. There is the need to embark on routine monitoring and surveillances by the regulatory agencies involved to ensure effective implementation of WHO water safety plans from the catchment source to the consumer. This could be enhanced by replacing old pipes with new ones Bottled water industries should be designated away from heavy metal industries.
